What are the physical properties of 10-Camphorsulfonic Acid?
10-Camphor sulfonic acid is also an organic compound. It has many physical properties, as detailed below.
Looking at its morphology, under room temperature and pressure, 10-camphor sulfonic acid is mostly in the shape of white crystalline powder, with fine texture. This morphology is easy to observe and use, and also makes it easy to operate in many chemical reactions and industrial processes.
When it comes to solubility, this substance is soluble in water, and can be well dispersed and dissolved in water to form a uniform solution. At the same time, it also has a certain solubility in common organic solvents such as ethanol and methanol. This good solubility makes it widely used in organic synthesis and drug preparation, because different solvents can be used to regulate the reaction process and product purity.
As for the melting point, the melting point of 10-camphor sulfonic acid is quite clear, about 197-201 ° C. The melting point is an important physical constant of the substance, by which the purity of the substance can be determined. If the melting point deviates from this range, it may suggest that it contains impurities.
In addition, 10-camphor sulfonic acid has a certain degree of hygroscopicity. In a humid environment, it is easy to absorb moisture in the air, causing its own weight to increase and its shape to change. This hygroscopicity needs to be paid attention to during storage and use. It usually needs to be stored in a dry place to prevent moisture absorption from affecting the quality and performance.
Furthermore, its aqueous solution is acidic. This acidity is due to the presence of sulfonic acid groups in the molecular structure, which can partially ionize hydrogen ions in water, so it has acidic characteristics. This acidity makes it play an important role in some acid-base neutralization reactions and catalytic reactions.
10-Camphor sulfonic acid has various physical properties, which are interrelated and jointly determine its application and value in many fields such as chemical industry, medicine, materials, etc. It occupies an important position in industrial production and scientific research.
10-Camphorsulfonic Acid What to pay attention to when storing
10 - When storing camphor sulfonic acid, pay attention to many matters. This substance has specific chemical properties and must be stored with caution.
The first thing to pay attention to is the temperature and humidity of the storage environment. It should be placed in a cool and dry place to avoid high temperature and humidity. High temperature can easily cause changes in its properties or cause chemical reactions; humid gas can also make the substance absorb moisture and deteriorate, damaging its quality and efficiency.
The second is related to the storage place. It should be kept away from fire sources, heat sources and oxidants. 10 - Camphor sulfonic acid is at risk of combustion and explosion in case of open flame, hot topic or contact with oxidants. Therefore, the place of storage must be well ventilated and adjacent to such dangerous objects.
Furthermore, the integrity of the package is of paramount importance. Its packaging must be tight to prevent leakage. If the package is damaged, not only the substance is vulnerable to external factors, but also the leakage may pose a threat to the environment and personal safety.
In addition, the storage area should be clearly marked, indicating that it is 10-camphor sulfonic acid, and related hazard warnings. In this way, personnel can see at a glance when operating and managing, avoid misuse and ensure the safety of the storage process.
What are the Synthetic Methods of 10-Camphorsulfonic Acid
10-Camphor sulfonic acid is synthesized by many methods. The ancient method often started with camphor and was prepared by sulfonation. Camphor is a common thing in nature, mostly derived from camphor trees. The method of sulfonation requires the selection of appropriate sulfonating reagents, such as concentrated sulfuric acid and fuming sulfuric acid. When concentrated sulfuric acid is used as a sulfonating agent, camphor is interacted with concentrated sulfuric acid at a suitable temperature and reaction time. However, this method also has drawbacks, such as harsh reaction conditions, many side reactions, and product separation and purification. After
there is a new method, which takes green chemistry as the case and uses mild sulfonating reagents, such as sulfur trioxide-pyridine complexes. This method has easy control of reaction conditions, few side reactions, and high product purity. During the reaction, camphor and sulfur trioxide-pyridine complex are mixed in a suitable solvent, and 10-camphor sulfonic acid can be obtained by stirring, heating and other operations. And this method is environmentally friendly and in line with the general trend of current chemical development. And ionic liquids are used as mediators. Ionic liquids have unique physical and chemical properties, which can make the reaction proceed efficiently, and the products are easy to separate. It is also a good method for synthesizing 10-camphor sulfonic acid. All synthesis methods have advantages and disadvantages, and they are all used according to different needs and conditions.
What is the market price range for 10-Camphorsulfonic Acid?
The price of 10-camphor sulfonic acid in the market often varies due to many reasons. The price involved is related to the source of production, quality, quantity and supply and demand in the market.
If its source is different, the production place is different, and the price is also different. The price of 10-camphor sulfonic acid of good quality may be higher than that of ordinary people. And those who are pure in quality are used in many ends. In medicine, chemical industry and other industries, those who need it are of high quality, so the price may be high.
The quantity is also the main reason. If the purchase quantity is large, the merchant may give a discount for profit, and the total price will drop. On the contrary, if you buy in small quantities, the price may increase.
As for the supply and demand in the market, if there are many people who want it, and the supply is small, the price will rise; if the supply exceeds the demand, the business will sell the goods, or reduce the price to promote the transaction.
Roughly speaking, under normal market conditions, the price per gram may be between a few yuan and a few tens of yuan. However, this is only an approximate number, and the actual price depends on the market conditions at the time. Those who buy this goods should pay more attention to the prices of various houses and compare the quality of the goods in detail, so that they can get good goods at a suitable price, so as not to spend improper money.
